摘要
利用粉煤灰、高效减水剂配制出了C60高性能混凝土。当粉煤灰掺量为16%,高效减水剂掺量为1.0%,高性能混凝土28d强度高达77.3MPa,CI-扩散系数低至1.52×10^(-9)cm^2/s,1m^3混凝土节省水泥约200kg。本课题即C60高性能混凝土的配制试验,为今后高性能混凝土在实际中的应用打下良好的基础。
the paper is the preparation of C60 high performance concrete with fly ash, superplasticizer and air entraining agent, when the ration of the fly ash is 15%, superplasticizer is 1.2%,the 28d strength of the concrete is 77.3 MPa, CI- diffusion coefficients is 1.52X 10-9cm2/s, the saving cement amount is about 200kg per 1m3concrete, the subject gets a good base for the further practical applying of high performance concrete.
